Description

Technical Field

[0001] This invention relates to the field of elevator technology, and in particular to a method for informing passengers of information during elevator operation. Background Technology

[0002] Currently, elevator systems typically provide passengers with the elevator's direction of travel and the current floor information. Additionally, for high-speed and variable-speed elevators, real-time speed information of the elevator car may also be provided, as per CN201110148452.0. However, when providing real-time speed information, passengers cannot immediately know which stage of the elevator's operation it is in (e.g., acceleration, constant speed, or deceleration). They must determine the current stage by observing and comparing the speed information at different times. Furthermore, even after determining which stage the elevator is currently in, it's still impossible to know how long the current stage will last or what other stages will follow (e.g., a constant speed phase may not exist in some cases). This is helpful for passengers riding ultra-high-speed elevators. During ultra-high-speed elevator operation, due to the extremely high speed, the gravitational acceleration and air pressure experienced by the elevator during acceleration, constant speed, or deceleration phases are different, which will bring different physical sensations to passengers, mainly physical discomfort. If passengers can anticipate the stages they will experience, they can prepare in advance to alleviate discomfort, just like passengers can swallow in advance to relieve discomfort during airplane takeoff.

[0003] Therefore, it is necessary to provide a means of informing passengers in advance of the stages the elevator will go through and the approximate duration of each stage. Summary of the Invention

[0016] Preferably, in step S5, passengers are informed of the current elevator position and the elevator operation stage they are about to experience by means of an identification group, wherein the identification group is composed of stage identifications corresponding to each operation stage in sequence.

[0017] Preferably, step S5, which involves informing the user, comprises the following steps: Step A1, selecting one of all available identifier formats as the selected identifier format; Step A2, determining the order of appearance of each elevator operation stage according to the speed graph; Step A3, determining the relative position of the stage identifier corresponding to each elevator operation stage in the identifier group according to the order of appearance; Step A4, constructing the identifier group using the stage identifier based on the relative position; Step A5, obtaining the current operation stage information of the elevator; Step A6, highlighting the stage identifier corresponding to the current operation stage of the elevator.

[0018] Preferably, the stage identifier includes a directional element that reflects the connection relationship between each stage identifier and the sequential relationship between each operation stage, and the connection relationship between the stage identifiers is consistent with the time sequence of the corresponding elevator operation stages.

[0019] Preferably, the information on each elevator operation stage is composed of different graphic identifiers, wherein the graphic identifier representing the current elevator operation stage is highlighted; the graphic identifier reflects the duration of each elevator operation stage.

[0020] Preferably, the method for the graphic identifier to represent the duration of each elevator operation stage is as follows: the length of the graphic identifier for each elevator operation stage is proportional to the duration of each elevator operation stage.

[0021] Preferably, the graphic identifier includes a progress identifier, which is used to indicate the remaining duration of the current elevator operation phase.

[0022] Preferably, step S5 determines whether at least one of the elevator operation stage information currently in progress and about to be experienced is the same as the previous notification result, and the current notification will only be executed if the determination result is negative.

[0023] The present invention also provides a method for informing passengers of information during elevator operation phases, wherein the elevator operation phases include an acceleration phase, a constant speed phase, and a deceleration phase, comprising the following steps:

[0024] Step S1: Obtain the current speed graph of the elevator during this run;

[0025] Step S2: Determine the elevator operation phases included in the speed graph;

[0029] Step S6: Monitor the current speed graph in real time. If the speed graph changes, return to step S1. If the speed graph does not change, return to step S3. Continue until the elevator completes this operation.

[0030] Preferably, when the speed pattern changes, the method for determining the elevator operation stage in step S2 is as follows: taking the start time of the speed pattern change, or the time corresponding to the earliest occurrence point of the different parts of the changed speed pattern compared to the original speed pattern, or the start time of the operation stage where the earliest occurrence point of the different parts of the changed speed pattern compared to the original speed pattern is located, the changed speed pattern part is taken as a new speed pattern, and the elevator operation stages it contains, as well as the occurrence order and duration of the elevator operation stages are obtained; the elevator operation stages corresponding to the parts already experienced in the original travel, as well as the occurrence order and duration of the elevator operation stages, are combined with the elevator operation stages contained in the changed speed pattern, as well as the occurrence order and duration of the elevator operation stages, to obtain the various elevator operation stages to be experienced in this travel.

[0031] Preferably, the information for each elevator operation stage is composed of different graphic identifiers, wherein the graphic identifier representing the current elevator operation stage is highlighted; the graphic identifiers corresponding to the original speed graphic remain unchanged, and the graphic identifiers corresponding to the new speed graphic are updated.

[0032] Preferably, when the elevator operation phases before and after the start time of the speed graphic change belong to the same operation phase, the graphic identifier is updated according to the change in the duration of the current elevator operation phase; when the elevator operation phases before and after the start time of the speed graphic change do not belong to the same operation phase, the identifier position corresponding to the change point is taken as the end point of the graphic identifier corresponding to the previous elevator operation phase, and the identifier position of the change point is taken as the starting point of the graphic identifier corresponding to the next elevator operation phase.

[0033] Preferably, updating the graphic identifier based on the change in the duration of the current elevator operation phase includes: calculating a metric value for the phase identifier corresponding to the combined operation phase based on the duration of the combined operation phase; keeping the starting position of the phase identifier unchanged, and changing the corresponding attributes of the phase identifier only based on the calculated metric value.

[0034] Preferably, the steps for determining the marker position of the change point are as follows: Step B1, determine the operating stage when the speed pattern changes; Step B2, determine the starting point of the operating stage; Step B3, determine the interval length between the speed pattern change point and the starting point of the operating stage; Step B4, calculate the marker length in the marker based on the interval length; Step B5, determine the stage marker and its starting point corresponding to the operating stage when the speed pattern changes; Step B6, the point corresponding to the marker length moved from the starting point is the marker position of the change point.

[0035] Preferably, when updating the graphic identifier, the proportional relationship between the length of the graphic identifier and the duration of the elevator operation phase is changed simultaneously; the proportional relationship is determined based on the changed duration of each elevator operation phase and the overall size of the corresponding graphic identifier.

[0036] Preferably, the position of the marker corresponding to the change point when the speed graphic changes according to the proportional relationship is adjusted, and the adjusted marker position is used as the end point of the graphic marker corresponding to the previous elevator operation stage, and at the same time, the adjusted marker position is used as the starting point of the graphic marker corresponding to the next elevator operation stage.

[0037] Preferably, when updating the graphic identifier, a progressive update method with multiple iterations is adopted, with each update amount being a preset scale change amount Δ.

[0038] Preferably, when updating the graphic identifier, the screen display is implemented in any of the following ways: Method 1: During each update, the position of the location identifier in the display screen remains unchanged, and only the rest of the identifier is updated.

[0045] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can fully understand other advantages and technical effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific embodiments, and the details in this specification can also be applied based on different viewpoints, with various modifications or changes made without departing from the overall design concept of the invention. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other. The following exemplary embodiments of the present invention can be implemented in many different forms and should not be construed as being limited to the specific embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary embodiments to those skilled in the art.

[0046] Example 1

[0047] Elevator operation stages refer to the various phases that an elevator goes through during its journey from startup to stopping at a floor, divided by the different speeds of the elevator car. Of course, the criteria for dividing elevator operation stages vary depending on the purpose, resulting in different stages. Here, our aim is to inform passengers in advance about the elevator stages they will experience, thus preparing them to mitigate potential discomfort. For simplicity, we roughly divide elevator operation stages into acceleration, constant speed, and deceleration stages. When the purpose of the division is to analyze the driving current of the elevator and / or the tension on the elevator suspension components (such as steel cables), it is preferable to further divide the acceleration stage into acceleration-increasing, constant speed-increasing, and deceleration stages, and the deceleration stage into similar further divisions. Since deceleration has the same properties as acceleration, acceleration and deceleration are uniformly referred to as acceleration in the claims.

[0048] Figure 1 The image shows the complete speed graph of the elevator during one movement.

[0049] To achieve the goal of informing passengers in advance about the elevator operation phases they will experience so that they can prepare to alleviate potential discomfort, this embodiment provides an elevator operation phase information notification method, wherein the elevator operation phases include an acceleration phase, a constant speed phase, and a deceleration phase, and includes the following steps:

[0050] Step S1: Obtain the speed graph of the elevator during this run;

[0051] Step S2: Determine the elevator operation phases included in the speed graph;

[0052] Step S3: Obtain elevator operation information, which includes at least speed information;

[0053] Step S4: Determine the current elevator operation stage based on the elevator operation information and speed graph;

[0054] Step S5: Inform passengers of the current elevator position and the elevator operation phase they are about to experience.

[0055] Step S6, return to step S3, until the elevator completes this run.

[0056] The reason for determining the elevator operation stages included in the speed graph in step S2 is that the elevator operation stages may differ in certain situations. For example, when the length of the elevator's current travel distance is very short, the elevator may not include a constant speed stage, or it may even directly enter the deceleration stage before the elevator car reaches the rated speed. When the travel distance is very short, it may even enter the deceleration stage just as it reaches the constant acceleration stage. In this case, the deceleration acceleration stage, the constant speed stage, and the acceleration and deceleration stages in the deceleration stage are not included. Therefore, it is necessary to determine them based on the speed graph.

[0057] In addition, the elevator operation information obtained in step S3 includes at least speed information, or further includes corresponding time information and / or acceleration (deceleration) information.

[0058] When at least speed information and acceleration (deceleration) information are acquired simultaneously, step S4 can determine the current operating stage of the elevator based solely on the acquired current information (because the speed-acceleration / deceleration corresponding to any two different elevators in the acceleration / deceleration stage must be different).

[0059] When speed and acceleration (deceleration) information are not acquired simultaneously, i.e., only speed or acceleration (deceleration) information is acquired, the points corresponding to the same speed and acceleration (deceleration) are not unique. Therefore, step S4 cannot determine the current operating stage of the elevator based solely on speed or acceleration (deceleration) information. To solve this problem, at least one piece of historical data (i.e., past speed information or acceleration (deceleration)) is saved in step S3, so that step S4 can combine historical data to determine the current operating stage of the elevator.

[0060] In engineering practice, after completing steps S1 to S5 for the first time, the process should return to step S3. If the current operating stage of the elevator, determined based on the newly acquired operating information, changes, passengers should be informed of the updated current operating stage of the elevator.

[0061] The specific rules for determining the current operating stage of an elevator are relatively simple and can be obtained through a little analysis based on relevant physics knowledge.

[0062] Preferably, step S5 determines whether at least one of the elevator operation stage information currently in progress and the stage to be experienced is the same as the previous notification result, and the current notification is only executed if the determination result is negative, thereby avoiding duplicate notification.

[0063] The information notification method for elevator operation phases in this embodiment provides passengers with information about the current and upcoming operation phases of the elevator, enabling passengers to make appropriate preparations and overcoming the shortcomings of existing technologies that cannot provide passengers with information about the current and subsequent operation phases.

[0064] Example 2

[0065] While Example 1 can provide passengers with information about the elevator's current and upcoming operating phases, allowing them to prepare accordingly, it has a limitation: it cannot inform passengers of the duration of each upcoming phase. This example attempts to address this limitation.

[0066] In this case, in step S2, the duration of each elevator operation phase is determined, and in step S5, the passenger is provided with the current elevator position and the duration of the elevator operation phase to be experienced.

[0067] Example 3

[0068] While Example 2 can provide passengers with the current and upcoming operating phases of the elevator, as well as the duration of the upcoming phase, it cannot inform passengers of the remaining duration of the current operating phase. This example attempts to address this deficiency.

[0069] In this case, the elevator operation information also includes time information corresponding to the speed information. In step S4, the remaining duration of the current elevator operation phase or the start time of the next elevator operation phase is calculated in real time.

[0070] Based on the remaining time and the order in which each operating stage occurs, the time interval from the start time of the next operating stage adjacent to this stage can be obtained, thereby enabling the prediction of the start time of the next operating stage adjacent to this stage and other operating stages.

[0071] Example 4

[0072] In this embodiment, the elevator operation information is communicated to passengers in a way that can be visually accepted by passengers, using patterns, graphics, etc. (hereinafter collectively referred to as logos).

[0073] In step S5, passengers are informed of the current elevator position and the elevator operation stage they are about to experience by means of an identification group, wherein the identification group is composed of stage identifications corresponding to each operation stage in sequence.

[0074] Specifically, step S5 involves the following steps for providing the notification:

[0075] Step A1: Select one of the available identifier formats as the selected identifier format;

[0076] The identifier can be a straight line, curve, arc, sector, cylinder, etc. These options must possess the attribute that its magnitude can be expressed numerically, such as the length of a straight line, curve, or arc, the angle of a sector, or the height of a cylinder. Of course, if a unique identifier is predetermined, such as a straight line, then this step of determining the identifier is unnecessary.

[0077] Step A2: Determine the order of occurrence of each elevator operation stage based on the speed graph;

[0078] Step A3: Determine the relative position of the stage identifiers corresponding to each elevator operation stage in the identifier group according to the order of appearance (i.e., the adjacent relationship between them is determined by the order).

[0079] Step A4: Construct the identifier group based on the relative position using the stage identifier;

[0080] Each operating phase is assigned a phase identifier, and these identifiers should be distinct for different phases (e.g., for linear phase identifiers, different colors can be used and / or the phase name can be displayed on the identifier). Based on the order in which the operating phases occur, the corresponding phase identifiers are arranged sequentially (e.g., connected end-to-end) and combined. The resulting identifier group corresponds to the entire travel distance of the elevator (because the entire travel distance is divided into operating phases according to their sequence, and the entire travel distance is obtained by connecting and combining the operating phases sequentially). Thus, an identifier group corresponding to the entire travel distance and composed of the phase identifiers is obtained. This identifier group remains unchanged during the elevator's travel distance (unless the speed graph changes, in which case the identifier group needs to be redefined).

[0081] Step A5: Obtain the current operating stage information of the elevator;

[0082] Step A6: Highlight the stage indicator corresponding to the current operating stage of the elevator. (Highlighting can be achieved through increased brightness, dynamic flashing, etc.)

[0083] Preferably, in order to better reflect the sequential relationship of each operation stage (the sequential relationship of the operation stages is determined by the order in which each operation stage appears), the stage identifier includes a directional element that reflects the connection relationship between each stage identifier and the sequential relationship between each operation stage, and the connection relationship between the stage identifiers is consistent with the time sequence of the corresponding elevator operation stages.

[0084] (For example, if the stage identifier is a horizontal straight line segment, set the left endpoint of the straight line segment as the start point of the stage, set the right endpoint of the straight line segment as the end point of the stage, and set an arrow pointing to the right at the right endpoint.) This can better reflect the connection relationship between each stage identifier and the sequential relationship between each operation stage.

[0085] Example 5

[0086] Example 4 can only indicate the current operating stage of the elevator, but it cannot give the relative position of the elevator in the current operating stage, that is, the information of the part that has been experienced and the part that has not yet been experienced in this stage.

[0087] This embodiment is an improvement on embodiment 4 in order to provide the relative position information of the elevator at its current operating stage.

[0088] The information for each elevator operation stage is composed of distinct graphic icons, with the icon representing the current elevator operation stage being highlighted; these graphic icons reflect the duration of each elevator operation stage. The length of the graphic icon for each elevator operation stage is proportional to the duration of that stage.

[0089] There are two specific methods:

[0090] Method 1

[0091] a) Determine the length of the graphic representation corresponding to the entire travel distance of the elevator;

[0092] b) Calculate the ratio of the length of the graphic identifier to the sum of the durations of each operational phase;

[0093] c) Calculate the product of the duration of each operating phase and the ratio, and use it as the length of the phase identifier of each operating phase, thereby determining the phase identifier of each operating phase.

[0094] d) Combine the stage identifiers of each operating stage according to the order of their occurrence. The resulting graphic identifier corresponds to the entire travel distance of the elevator.

[0095] Method 2

[0096] A. Determine the scaling factor between the state marker length and the state duration (similar to the scale bar in a map);

[0097] B. Calculate the product of the duration of each operating phase and the proportional coefficient, and use it as the length of the phase identifier of each operating phase, thereby determining the phase identifier of each operating phase.

[0098] C. Combine the stage identifiers of each operating stage according to the order in which they appear. The resulting graphic identifier corresponds to the entire travel distance of the elevator.

[0099] The adjusted stage markings reflect the duration of each operating stage, providing a basis for subsequently marking the relative position of the elevator in the current operating stage on the graphic markings (stage markings).

[0100] Preferably, the graphic identifier includes a progress identifier, which is used to indicate the remaining duration of the current elevator operation phase. After obtaining the specific actual position of the elevator in the current operation phase, the remaining duration of the current operation phase and the time until the start time of subsequent operation phases can also be obtained and displayed, as described in Embodiment 3.

[0101] Example 6

[0102] In the aforementioned embodiments, steps S1 and S2 are performed under the assumption that the velocity profile is obtained before the elevator starts moving and thus begins a travel distance, and that the velocity profile does not change during the movement of the elevator car. However, in reality, after the elevator begins moving, i.e. during the current travel distance, the velocity profile often changes for various reasons. For example, after a variable-speed elevator starts moving, it redetermines the maximum speed and / or acceleration for subsequent movements based on the precise value of the friction force obtained, and then re-plans its velocity profile for subsequent movements; if a destination floor earlier than the current travel distance is added in the elevator car and / or on a floor during the elevator car's movement, causing the elevator to shorten its original travel distance, the velocity profile on which the subsequent elevator car movement depends must be changed accordingly, and so on.

[0103] To address the situation where the speed profile changes during the car's travel, this embodiment provides an elevator operation phase notification method, which includes an acceleration phase, a constant speed phase, and a deceleration phase, and includes the following steps:

[0104] Step S1: Obtain the current speed graph of the elevator during this run;

[0105] Step S2: Determine the elevator operation phases included in the speed graph;

[0106] Step S3: Obtain elevator operation information, which includes at least speed information;

[0107] Step S4: Determine each elevator operation stage based on the elevator operation information and speed graph;

[0108] Step S5: Provide passengers with information on the current and upcoming elevator operation phases;

[0109] Step S6: Monitor the current speed graph in real time. If the speed graph changes, return to step S1. If the speed graph does not change, return to step S3. Continue until the elevator completes this operation.

[0110] When an elevator speed profile changes during its travel, the elevator has already begun that journey, meaning it's already in a certain phase of operation. The original travel distance is thus divided into the already completed portion and the portion yet to be completed. When the speed profile changes, it alters the portion of the original travel distance that hasn't yet been completed. Furthermore, to ensure continuous and comfortable elevator operation, the changed speed profile must connect seamlessly with the portion of the original travel distance already completed (usually a smooth transition).

[0111] Therefore, when the speed pattern changes, the method for determining the elevator operation stage in step S2 is as follows: taking the start time of the speed pattern change, or the time corresponding to the earliest occurrence point of the different parts of the changed speed pattern compared to the original speed pattern, or the start time of the operation stage where the earliest occurrence point of the different parts of the changed speed pattern compared to the original speed pattern is located, the changed speed pattern part is taken as a new speed pattern, and the elevator operation stages it contains, as well as the occurrence order and duration of the elevator operation stages are obtained; the elevator operation stages corresponding to the parts already experienced in the original travel, as well as the occurrence order and duration of the elevator operation stages, are combined with the elevator operation stages contained in the changed speed pattern, as well as the occurrence order and duration of the elevator operation stages, to obtain the various elevator operation stages that will be experienced in this travel.

[0112] It should be noted that when performing the above combination, the last running stage corresponding to the part already experienced in the original travel may be the same as the first running stage corresponding to the changed speed pattern (these two running stages are combined together as one running stage, and its duration is the sum of their durations), or they may be different (as two adjacent different running stages).

[0113] The aforementioned embodiments address how to determine which operating stages are included in the elevator's travel distance and which stage it is currently in, and then inform passengers of the results. No restrictions are placed on the specific form of this information notification.

[0114] Example 7

[0115] As described in Embodiment 6 above, the elevator's speed graph may change during its travel, and obviously the graphic identifiers should also be changed accordingly. This embodiment will specifically discuss the changes to the graphic identifiers.

[0116] As described in Embodiment 6 above, when the elevator speed graph changes during its travel, the actual travel of the elevator is divided into two parts: the first part corresponds to the original speed graph, and the second part corresponds to the new speed graph. The method for dividing these two parts is the same as described in Embodiment 6 above. Both parts have corresponding graphic identifiers, and it is obvious that the graphic identifiers corresponding to the new speed graph have changed relative to the original graphic identifiers, requiring updates using the graphic identifiers corresponding to the new speed graph.

[0117] There are two ways to implement updates:

[0118] Method 1: In this method, the identifiers corresponding to the original speed graphic remain unchanged; only the corresponding graphic identifiers are updated based on the new speed graphic. This update includes the name and quantity of the graphic identifiers for the subsequent operating stages (and, when the identifiers contain duration information, also the actual values ​​of the attributes corresponding to the duration of the operating stage (such as the length of the straight segment used as a stage identifier)). It is important to emphasize that when implementing this update for graphic identifiers corresponding to the elevator's current operating stage, it is crucial to distinguish whether the corresponding operating stages before and after the change belong to the same operating stage. If they belong to the same operating stage, the graphic identifiers should be updated according to the change in the duration of the current elevator operating stage.

[0119] Specifically, this includes: calculating the duration of the combined operation phase to obtain a metric value corresponding to the phase identifier of the combined operation phase; keeping the starting position of the phase identifier unchanged, and only changing the corresponding attributes of the phase identifier according to the calculated metric value (e.g., if the identifier is a sector, the duration corresponds to the sector's metric value—angle; the starting edge of the sector remains unchanged, and only the ending edge of the sector is adjusted according to the metric value—angle; for a long strip identifier, the duration corresponds to the length of the long strip identifier, keeping the starting point of the long strip identifier unchanged, and the change in the duration of the combined operation phase is reflected in the change of the ending point of the long strip identifier).

[0120] When the elevator operation phases before and after the start of the speed graph change do not belong to the same operation phase, the position of the marker corresponding to the change point is taken as the end point of the graphic marker corresponding to the previous elevator operation phase, and the position of the marker corresponding to the change point is taken as the start point of the graphic marker corresponding to the next elevator operation phase.

[0121] The steps for determining the location of the change point identifier are as follows:

[0122] Step B1: Determine the operational stage when the velocity graph changes;

[0123] Step B2: Determine the starting point of the current operational phase;

[0124] Step B3: Determine the interval length between the point of change in the velocity graph and the starting point of the current operating phase;

[0125] Step B4: Calculate the length of the marker in the marker based on the interval length;

[0126] Step B5: Determine the stage identifier and its starting point corresponding to the operating stage when the speed graph changes.

[0127] Step B6: The point corresponding to the length of the marker after moving it from the starting point is the marker position of the changed point.

[0128] In this method, the marker position corresponding to the actual position of the elevator in the current operating phase (see Example 5) and the markers located before the marker position corresponding to the actual position remain unchanged during the update process, and their positions also remain unchanged.

[0129] Method 2: In this method, when updating the graphic identifier, the proportional relationship between the length of the graphic identifier and the duration of the elevator operation phase is changed simultaneously; the proportional relationship is determined based on the changed duration of each elevator operation phase and the overall size of the corresponding graphic identifier.

[0130] Adjust the position of the marker corresponding to the change point when the speed graphic changes according to the aforementioned proportional relationship. Use the adjusted marker position as the end point of the graphic marker corresponding to the previous elevator operation stage, and use the adjusted marker position as the starting point of the graphic marker corresponding to the next elevator operation stage.

[0131] The ratio between the length of the graphic identifier and the duration of the running phase will be changed in order to make the overall size of the travel identifier corresponding to the new travel (including the part before and after the change) appropriate (e.g., keep the overall size unchanged, the travel identifier is neither too large nor too small).

[0132] After obtaining the graphic identifier and its location, since at least a part of the graphic identifier and its location have changed, a simple and direct update would confuse passengers and cause problems such as abrupt changes in displayed content and screen flickering. Therefore, a gradual update method with multiple iterations is adopted when updating the graphic identifier, with each update amount being a preset scale change Δ. Specifically, when updating the graphic identifier, the screen display is implemented using any of the following methods:

[0133] Method 1: During each update, keep the position of the location marker in the display screen unchanged, and only update the rest of the marker. After the scale reaches the new scale, move the entire display screen according to the principle of adapting the display content to the display area so that all display content can be displayed in the display area.

[0134] Method 2: During each update, while fine-tuning the display position of the content to keep the boundary of the content always aligned with the boundary of the display screen, gradually move the position marker to ensure that the display screen always displays all content during the update process.
